Abstract (en)
This invention relates to a guide for a high speed steel rolling mill. The guide comprises two rolling members (between which the work product passes) mounted for rotation on a base member. Each roller has a frusto-conically shaped bearing recess formed therein and each guide roller is mounted on a mating, frusto-conically shaped projection which protrudes from the base member. Each of the projections has a central oil duct which serves to feed a lubricating oil under pressure into the frusto-conically shaped space between the roller and its mating projection. The lubricating oil serves to form a film between the stationary projection and the rotating guide roller. Because of the conically shaped mating surface, the lubricating oil tends to "lift" the guide roller from the surface of the supporting base. Each rolling member is provided with a vane structure to permit the rolling member to be prespun by the impingement of a cooling fluid on the vane surface thereof. <IMAGE>
